Title: Filtering apparatus for separating solid and suspended matter from a liquid
Inventor: KLEIN WALTER
IPC: B01D29/62
Filed: 1990-07-17
Abstract: ABSTRACT OF THE DISCLOSURE:      A filtering apparatus for separating solid and suspended matter from liquids  includes a cylindrical housing, a cylindrical filter basket coaxially installed therein and delimiting a space I receiving the liquid to be filtered relative to an external annular space II receiving the filtratre, and a  backflushing device axially displaceable by means of a drive and including at least one piston disc provided with a channel connecting  the  external  annular  space  II,  via perforations provided in the filter basket,   with a hollow space III of a central tube provided coaxially with the filter basket and carrying the piston disc. The piston disc lies at the interior surface of the filter basket via seals. In order to be able to filter non-lubricating,  aggressive  and  abrasive  media  by safeguarding a long service life and a low susceptance to failure of the filtering apparatus, the central tube constitutes a movable structural unit together  with the piston disc and a discharge tube for backflush liquid running into the cavity III of the central tube.  A dynamic seal is provided between the axially movable central tube and the housing. The drive engages at the closed end of the central tube carrying the discharge tube.

Title: Roll for use in the production of paper and method for the manufacture of the roll
Inventor: LEINO JORMA
IPC: C23C4/02
Filed: 1990-10-23
Abstract: The invention concerns a roll for use in the production of paper, in particular a renter roll in a press section of a paper making machine, with which the web is in direct contact and from which the web is detached.  In the invention, a composite structure has been formed onto the cylinder mantle of the roll.  According to the invention, the roll face is provided with a surface layer which protects the roll from wear and which provides good properties for detaching of the web, this surface layer being formed by thermal spraying of a powder wherein metal and ceramic phases are in the same powder particle.  The roll face is additionally provided with a dense layer for protection against corrosion, which layer is made of stainless steel whose chromium content is 10 to 29% and which layer is placed between the surface layer and the roll mantle.  The function of the layer for protection from corrosion is to protect the roll mantle from corrosion and to promote the adhesion of the surface coating to the roll.  The invention also concerns a method for the manufacture of the roll.

Patent CA-2034870-A1 (CA)
Inventor: PATTON PAUL B
IPC: G05B19/409
Filed: 1991-01-24
Abstract: The position of the power output member of a motor actuator which is normally controlled by a microprocessor in response to system-supplied condition signals may be set manually by providing a manually controlled selector signal to the microprocessor allowing manually controlled adjustment signals rather than the normal condition signals to form the parameters from which is derived the motor control signal  In the preferred embodiment, a first switch generates the selector signal and a second switch generates the adjustment signal.  Such apparatus allows a repairer or installer to adjust a mechanical positioning system driven by the motor actuator while the positioning system is in a variety of precisely selected positions.          This control system system contains a feature allowing one to change position of the motor actuator's power output member either continuously or incrementally by appropriately manipulating the switch which generates the adjustment signal.

Title: Method for reducing the search complexity in analysis-by-synthesis coding
Inventor: MAZOR BARUCH
IPC: G10L19/12
Filed: 1991-03-04
Abstract: A method of encoding speech includes a limited search of a tree-code excitation codebook with a closed loop gain calculation for each test path under consideration. The gain calculation occurs when minimizing an error distance measurement between a synthetic signal defined by each test path being considered and the appropriate speech signal by optimizing a scaling factor of the synthetic signal. The encoding method achieves a significant reduction in computational complexity with minimal loss of performance.

Title: Tamper evident closure
Inventor: SCHMIDT FRANK J
IPC: B65D65/26
Filed: 1991-06-26
Abstract: ABSTRACT OF THE DISCLOSURE          This relates to a tamper indicating closure which includes a closure cap having a button which is movable between an elevated position and a downwardly recessed  position  in  accordance  with  the  state  of closure  of  an  associated  container.  In  particular, the  button  is  provided  with  a  tamper  indicating arrangement which will include a first layer directly attached to the button and an overlying second layer which  is  connected  to  the button generally at the periphery  thereof.  The  first  layer  is  in  the  form of a photoactive layer and the second layer is in the form  of  a  friable  filter  material.  Normally  the second layer protects the first layer,  but when the button changes its shape, the friable filter layer will crack and expose the underlying photoactive layer to cause a change in the photoactive layer. This change could be in the form of the disappearance of a message, including a UPC code or the developing of a previously formed message on the photoactive layer so as to make that message appear.

Title: Sparking stylus for acoustic digitizer
Inventor: KELLY WILLIAM
IPC: G06F3/043
Filed: 1990-02-20
Abstract: A stylus body is provided and has a generally elongated shape. A  tip member (220) extends from the front of the stylus body, the tip member preferably being elongated and narrowing to a point at its front end. A pair of spaced conductive wires (280) are disposed in said tip member. A plurality of apertures (223) are provided in the narrowing portion of the tip member, these apertures permitting efficient emission of acoustic energy from the spark gap at the wire ends. By having the spark gap substantially centrally within the tip member and close to the stylus point that contacts the working surface, the errors and inconsistencies that can result from different rotational orientations and/or tilts of the stylus are minimized.

Patent CA-2049236-A1 (CA)
Inventor: HAUT RICHARD C
IPC: F25J3/02
Filed: 1991-08-15
Abstract: The invention relates to a method and apparatus for start-up, transformation from start-up to normal operation and normal separation of carbon dioxide and other acid gases from methane using a distillation column with a controlled freezing zone. Normally, the feedstream is treated in at least one distillation zone, a controlled freezing zone, and another acid gas stripping apparatus. The freezing zone produces a carbon dioxide slush which is melted and fed into a distillation section and a methane-enriched stream which is fed to a separate stripping unit. Start-up is accomplished by refluxing the product stream from the separate stripping unit to the distillation column. Transformation is accomplished by separating the methane-enriched stream produced by the freezing zone into a liquid component for refluxing to the column and a vapor component to be fed to the separate stripping unit.

Title: Superabsorbent-coated aramid yarn and a process for manufacturing such a yarn
Inventor: GEURSEN HERMAN J
IPC: D06M101/30
Filed: 1991-10-25
Abstract: An aramid yarn, preferably poly(p-phenylene terephthalamide), is coated with a water swellable superabsorbent material. The swelling value of the yarn is at least 60. The superabsorbent provides water blocking capability to the yarn, so that it is suitable for use as a strength member, for example, in water tight optical communication cables. The yarn is made by successively treating an aramid yarn with a water-in-oil emulsion, a superabsorbent material being present in the water phase of the emulsion, and removing the liquid components from the treated yarn by evaporation.
